The electronic pressure gauges of the series DMG 3 measures overpressure, vacuum, difference- and absolute pressure and velocity of flow in air and non aggressive gases. These measuring values are directed to a 0-10 V analog output. They are shown on a 3.5-digit LED-display with a figure height of 14.2 mm. Because of used piezoresistive cells the pressure gauge reaches high reliability and precision. The aluminium housing has a high mechanical stability and good EMC- properties. It is suitable for installation into a control switchboard. The user is warned against overload pressure by a red LED on the front. An individual calibration certificate belongs to every delivered pressure gauge. The DMG 3 can be completed with several additional options:
